Description
technical field [0001] The invention relates to the field of pulse power supply design, in particular to a switch driving circuit of the pulse power supply. Background technique [0002] High-voltage pulse power supply is a kind of pulse power supply with adjustable output amplitude, period and width by adding switching circuit on the basis of high-voltage DC power supply. The switches used in high-voltage pulse power supplies mainly include gas switches, solid-state switches, and plasma switches, among which solid-state switches can be subdivided into power semiconductor devices such as IGBTs and MOSFETs. [0003] The driving circuit of the solid-state switch in the existing pulse power supply is as attached figure 1 and 2 As shown, the leading and trailing edges of the switching signal are respectively triggered to generate narrow pulses at the low-voltage end, and then transmitted to the high-voltage end through the leading edge pulse transformer and the trailing edge p...
